4.5 Post-connection check
Carry out the following checks after electrical connection:
Current output simulation:
1. Hold both arrow keys down (see "Display and operating elements" chapter) and connect the
analyzer to the power supply. Wait until the display shows "0 mA".
2. At your PLC, PCS or data logger, check whether the same current value is applied.
3. Press the
F
key. This allows you to browse to the next current values (4, 12, 20 mA,
depending on the setting).
4. Check that the current values in question are also present at your PLC, PCS or data logger.
5. If the values are not present:
a. Check the terminal assignment for analog output 1 or 2.
b. Disconnect the analog outputs from your PLC, DCS or data logger and repeat steps 1-4 but
this time measure the current values at the terminals of the analyzer and not at the PLC,
DSC or data logger.
If these current values are correct, please check your PLC, DCS, the data logger and/or the
electrical cables.
Device status and specifications Note
Are the analyzer or cables damaged externally? Visual inspection
Electrical connection Note
Does the supply voltage correspond to the data on the nameplate? 230 V AC / 50 Hz115 V AC / 60 Hz
Are current outputs shielded and connected?
Do the mounted cables have adequate strain relief?
Is the cable type route completely isolated? Guide power supply and signal lines
separately over the entire travel distance.
Separate cable ducts are ideal.
Cable run without loops and crossovers?
Are power supply and signal lines connected correctly according to wiring
diagram?
Are all screw terminals tightened?
Are all cable entries mounted, tightened and leaktight?
Interference suppressor at the analog output?
